To all whom it may concern: Y

Be it known that I, GEORGE A. GUsrAr.- SON, a citizen of the United States, residing at Churchs Ferry, in the county of Ramsey, State of North Dakota, have mvented oertain new. and useful Improvements in Spring- Wheels; and I do herebydeclare the following to be afull, clear, and exact description df .the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has reference to' improvements in spring wheels l designed primarily for use on motor cars, and iterms to provide an exceedingly sim leinexpen sive and generallv efficient yw eel ofl that type possessed of ther requisite lightness, strength, and durability.

To this end the invention, brieiiy described, resides in the .provision of a wheel in which the metallic -rim is connected tothe hub by four main spokes arranged at rightangles to each other, and by a similar number of pairs of secondary-spokes located between the main spolfes, each of the several spolres comprising a pair of telescoping members-yieldingly held in position with relation to each by meansof coll-springs, each of the main spokes being further connected with the rim by a pair of cross-braces disposed on opposite sides thereof and likewise arranged at right-angles thereto.

yThe invention will be readily understood from a consideration of the following detailed description, and its preferred embodiment is illustrated in the accompanying drawings in which like parts are designated by corresponding reference numerals, throughout the several views.

Of the said drawings, Figure 1 is a front elevation of a wheel constructed in accordance with the present invention, Fig. 2 is a vertical section therethrough, Figs. 3, 4, and 5, are sections taken respectively on the lines 3 3, 4 4, and 5 5, of i? ig. 2.

Referring more particularly to the drawings, 7 designates the U-shaped steel rim, 8 the hub, and 9 and 10 the main and secondary spokes respectively, which connect the rim and hub, there being four main spokes which are arranged at angles of 90 to each other.

Each of the main spokes consists as shown of a pair of telescoping members 11 and 12, the former of which in each instance is in the nature or" a hollow sleeve, which pivoted atv 'member 12 which latter is its `outer ends between a pair of ears 13 formed on or'secured to the under face of the rim, the two members of each main spoke being forced yieldingly apart fromA each other by means of an eXpansible coil-spring 14 interposed within the outer members- 11 'andbearing against the inner end of the out-er ends between ears 15 ormed on the hub. The member 12 of the main spoke is provided in addition, witha transversely- 1s osed pin 16 which extends at opposite ivoted at its en s through registering slots 17 formed in A the corresponding outer membfer 11. Each ofthe main spokes is further connected with the steel rim by means of a pair of cross braces 18 which are disposed upon opposite sides thereof and are arranged at right-angles thereto and in alinement with each other. Each c'iioss-brace'likewise consists of a pair of telescoping members 19 and 20.

yieldingl 4forced away from each other by expansib e coil-springs 21 located within the member 19 thereof and bearing against the inner end of the member 20 which latter has formed thereon a collar 22 between whichand the corresponding member 19 a second coil-spring 23 is located, said last-mentioned Isprings embracing the members 20. The

several cross lbraces are slightly bowed so as to permit them to cross each other.

A The secondary spokes 10 above referred to are arranged in pairs betweenleach pair of main spokes and the'members of each of the secondary spokes therefore pass upon opposite sides of the corresponding air of intersecting braces, as shown. Eac .of thelsecondary spokes in like mannerconsists lof a. pair of telescoping members 24 Aand 25 the v atter of which is pivotally connected 'at its outer end to ears 26 formed on the hub and extends 'at its opposite end into the corresponding member 24, being provided adjacent such oint with a transversely disposed pin 27 wiich extends at opposite ends through registering longitudinal slots 28 formed in the member 24 which latter is likewise pivotedto ears 29 formed on the wheel rim. l The members of each secondary spoke are normally forced away from each other by a coil-spring 30 disposed within the member 24. l

The U-shaped construction of the wheel rim 7 results in the rovision of an annular seat in which a soli rubber tire 31l is disposed.

The pairs of secondary spokes diverge from each other in their assage from the wheel rim to the hub, the nib ears to which said spokes are connected being formed adjacent the opposite face of the latter.

It will be apparent from the foregoing that the members of each of the several s okes are capable of movement towards and rom each other by reason of their telescopic connection, thus compensating at all points for the compression of the Wheel.

it hat is claimed, is,

l. ln a spring wheel the combination, with a hub and rim of a series of resilient main spokes arranged at right-angles to each other; a pair' ol alining resilient braces arranged on opposite sides of each main spoke at right-angles thereto, said braces being connected at opposite ends to the rim .and to said main spokes; and a pair of resilient secondary spokes disposed between each air ci main spokes, the spokes of each secon( ary pair div/erging from each other in their passage from the rim to the hub, to permit the passage ol the cross braces to the rim.

2. ln a' Spring-wheel, the combination,

with a hub and rim, of la series of resilient.

main spokes connecting said parts and arranged at right angles to eac i other, each spoke comprising a pair of teleseoping members, and ineans for yieldingly forcing the same in opposite directions; a pair of alining resilient braces arranged on opposite sides of each main spoke at right-angles thereto, said braces being connected at opposite ends to the rim and to said main spokes and a pair of resilient Secondary spokes disposed between each" pair of' spokes, the spokes of each secondary pair diverging from each other in their' passage from the rim to the hub, to permit the passage of the crossbraces to the rim.

' l3. In a spring-Wheel, the combination, with a hub and rim, of a series of resilient main spokes connecting said parts. and arranged at right angles to each other, each spoke comprising 'a pair o'l" telescoping meme bers, each outer member being provided with A a pair of registering slots, and each inner member with a transverse pin extending at opposite ends therethrough; means located Within the outer member of each spoke and etween each pair of spokes,

the spokes of each secondary pair diverging from each other in their rim to the hub, to-permit t cross-braces to the rim.

4. In a springmfheel, the combination,

assage from the e passage of the vwith a hub and rim', of a series of resilient main spokes connecting said parts and arranged at right an les to each other; a pair oir' a ining resilient races arranged on op osite sides of each main spoke, and at rig 1tangles thereto, each brace com rising a pair of telescoping members, an means for yieldingly forcing the same in opposite directions; and a pair of resilient secondary spokes disposed between each pair of spokes, t e spokes of each secondary pair diverging from each other in their' rim to the hub, to permit cross-braces to the rim.

5. In a spring-wheel, the combination, with a hub and rim, of a series of resilient main spokes arranged at right-angles to each other; a pair of alining resilient braces arranged on opposite sides of each main spoke at right-angles thereto, said braces bein connected at op osite ends to the rim anc to said main spo res; and a pair of resilient secondary s okes dispo'sed'between each air oi main spo es, the spokes of each secon ary pair diverging from each other in their pas sage from the rim to the hub, to permit the passage of the cross-braces to the rim, each main and secondary spoke, and each brace comprising a pair of telescoping members, and means for yieldingly forcing the same in opposite directions. f

In testimony whereof, I affix my signature, in preseneeof two Witnesses.
